This document describes part-number-specific changes recommended operating conditions revised electrical specifications, applicable, from those described general MPC7457 RISC Microprocessor Hardware Specifications (Order MPC7457EC). MPC7457 MPC7447 implementations PowerPCmicroprocessor family reduced instruction computer (RISC) microprocessors. Specifications provided this document supersede those MPC7457 RISC Microprocessor Hardware Specifications, Rev. later, part numbers listed Table only. This document primarily concerned with MPC7457; however, unless otherwise noted, information herein also applies MPC7447 part numbers listed Table Specifications addressed herein unchanged. Because this document frequently updated, refer your Motorola sales office latest version. Note that headings table numbers this document consecutively numbered.
